I would like to say that this is very risky decision and would urge you to reconsider. Few things:
- Having an alternative source of full VTXO tree will enable all users to have unilateral exits in case Ark server is down
- Multiple mirrors of VTXO tree will build redundancy and transparency among users towards actions of Ark server. In absence of this, Ark server could be akin to a custodial bitcoin exchange
Analogously even in bitcoin ecosystem, if your non custodial wallet always shows balance/history, the need of a blockexplorer can be debated. However with our multiple interactions with merchants, we have seen cases where the sender claims he sent funds but they don’t show up in receiver wallet. Having a blockexplorer provides a neutral source of truth that provides all actors in the ecosystem an incentive to remain honest.
I envisage explorers in Ark visualize VTXO tree of different servers and provide comparison of their fee, round timings , server downtimes, round participation BTC volumes etc. Work done in Arké MacOS prototype - #12 by Christoph is quite interesting and can be built upon
